I normally run a Super 6 Lil' Dune Racer at 12V, and recently had a sibling race against an 18V Porsche 911 GT3. The Porsche came out on top, and the driver of the Dune Racer wanted more power so he could reclaim the championship. Although the Lil' Dune Racer clearly can't handle 18V for a sustained period of time, I kicked it up for a few laps to see how it would do against the Porsche. 18V made the Lil' Dune Racer a rocket!
